how to identify relaxed constraints?

[yanda1234]

Hi Dr. Zimmerman,

I encountered a power flow case that could not be converged using DCOPF. However, after using toggle_softlims to relax some constraints, the DCOPF problem was able to converge successfully. The problem is when I tried to use commands below to identify which constraints are relaxed, I found none of them is relaxed. Do you know how could this happen? If none constraints needs to be relaxed, then why cannot original case get converged? DCopf.softlims.PMAX.overload~=0, DCopf.softlims.PMIN.overload~=0, DCopf.softlims.RATE_A.overload~=0

Kindly advise.

Best, Yanda
